Basically you have just lost the "STORE" function of the relay, and are in "USE" function all the time. Sounds fine until you can get it fixed to have the "STORE" mode.
We put the switch in "STORE" mode whenever on external power to isolate he batteries from the poor quality stock charger/converter to take better care of our batteries. We let the solar system charge the batteries.
